STOP AND WASTE COCK.

"lo all who/n. it 'muy cult-cern:

Be it known that I, bENJAMIN W. lloa'rEN- REITER, a citizen ofthe United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Stop and laste Cocks, of which the following is a specification.'

This invention relates to certain new and useful improvements in stop and waste cocks ro and it consists in theconstruction and coinbination of the parts whereby I provide a stop and waste cock which may be used as a supply and draw-off cock, said cock having four ports or ways in the casing and two ports or ways in the plug. Said plug when turned in one direction opens the main ports or ways and cuts oi vthe waste-pipes.

The stop and waste cock is designed to be applied to a water-supply pipeand its couzo nections, so that when the plug is turned in one direction water will pass through the valve-easing in the usual way7 and when the plug is turned in an opposite direction the water-supply will he cut oli and the pipe 2 5 which leads to thehouse-su ppl y will be placed in communication with the waste-port of the plug, the hot-water supply or the iireback and boiler being also connected with the waste-pipe, so that the entire system of piping, including the stand-boiler and lireback, will be drained when the water-supply to the house is eut oli. f Y.

In the accompanyingdrawings, whiclrili-u's trate my invention, Figure 1 is a diagram view 3 5 showing one manner of applying my improved stop and waste cock to the water-supply pipe. liig. 2 is a perspective view; Fig. 3, a horizontal sectional view, and Fig. 4 a vertical section. Y f

Referring to the drawings, A represents the casing of my improved stop and iva-ste cock, the same having passage-ways A. directly through the cock and means for coupling thereto the water-supply pipes. At right angles to the passage-ways Af the valve-casinghasa passage-way A2, and opposite thereto is an outlet A3. These several passage-ways c constructed so that there may be coupled thepeto pipes, and as an illustration `of one 5o torni-pf applicati nof inyimprovement'l have \|n l1 rg lf thc `drawings a diagram sl mwii,

vbe observed that the openings are on aline .with the opening b in the valve or plug and view in which pipe 1 is coupled to'one of the passage-ways A', and on the opposite passageway a pipe 2 is coupled, said pipe leading to the house-supply and having a branch which extends to the stand-boiler. From the standboiler there extends the usual hot-water-supply pipe and pipes which lead to the waterbaek and from said water-back to-the boiler, said pipe 3 being connected to the passageway A of the valve-casing, while the other passage-way'A3 is connected to awaste-pipe 4. The plug B, which is used with the valve-casing having the four ways, hereinbefore referred to, is of the usual type as to construction, 'inasm uch as it is provided withan opening' l), which extends transversely through the plug, and with a waste opening' or port b', which is positioned on a line with the opening av of the way A. The opening b or trans- 7o verse slot of the plug is of such a length thatv it will register when vturned with the opening a'3 and with the openings or direct ways a a4.

lu the cnstruction of this valve-casing it Will that the opening a2 is out of plane of the opening b of the, plug. The valve or plugB is provided with the usual handle and has stops which limit the movement of the valve to a 8o quarter-turn.

When the valve or plug is turned so as to bring the main portb hr register with the ap- *ert'ures or ports a ai, the cold water will flow through the pipes l and 2 to the house-supply and there will be no communication with thepipe 3 from the stand-boiler and waterback and the waste-pipe. When itis desired to out oi the water-supply, the valve-stem is given a quarter-turn, which brings the port b 9o through the valve in line with the openings a2. ai and the port ZJ in line with the port a", to which the house-supply pipe 2 is coupled. YV hen the valve is arranged in such position as is shown in Fig. 3 of the drawings, the wa.- ter in the house-supply pipe above the valvecasing A will be drawn oi through the openings b b in the valve, passing to the wastepipe 4 through the opening a3. In addition to draining the house-supply pipes the water zoo from the stand-boilerand water-hachs drawn ofi through ihepipe fi, which connects with
